SPECIFICATION forming part of Letters Patent No. 768,242, dated August 23,

Application filed April 27, 1904- enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved. means for insulating the wires in so-called concealed work; and it consists, essentially, of a rosette having a base or block formed to re-v ceive the ends of the two wire tubes. which are arranged better to insulate the wires by protruding from the wallor ceiling, and of a cap entirely covering the block and provided with means for securing it in position.

My invention will be understood by referenee to. the drawings herewith, in which the same reference letters and numerals of the i specification indicate the same parts in all the figures. 1 I

Figure I is avertical cross-section showing the rosette secured in position on the ceiling... Figs. II and III arerespectively bottom plan and side elevation 'of the block. Figs. IV

' and V are respectively, bottom) plan and top plan of the cap. Fig. VI is atop plan of the assembled rosette, showing the tubes in section. Fig. VII is a vertical section showing .the use of the cap without theblock.

In the figures, A indicates the block, formed with the opposite recesses 1 1 sufiiciently large to receive the ends of the wire tubes 2 2 of all ordinary sizes. From the tubes the ends of the WiI'6S4L are brought through the wire-holes 3 3 adjacent to the wire-terrninals 6 6, secured in their seats 9 9 by screws 7 7, having their heads arranged in Each terminal carries twov binding-screws, respectively, for the wire 4 and the cord. The central reinforce ment 11 for strengthening the block is pro Vided with a depression for receivingand cuiting.

ger of cutting the insulation and short-cir- The block is secured in position against the ceiling by securing-screws in holes 13 13, having their heads arranged'in depressions 14 14, by which they are separated from the terminals. On opposite sides the block is provided with notches 16 16 to engage with columns 17 17 on the inside of the cap B, guiding the arrangement of the parts and provided with screw-holes 15 for the cap-securing screws to hold the caplclos'e up against the ceiling, entirely covering and protecting the block and rendering it unnecessary to glazethe' latter. isprovided with reinforcing-ribs 2O 20, cut away at 21 21 to afford additional space for the wires and cords attached to the terminals. On the lower surface of the cap is the boss 23, formed with an inner cavity 24: and with a cord-hole 25 to receive the knot and to permit the cords to depend. I

The important feature of my invention is that it supplies a positive insulation between Heretoi'ore it has been common to arrange the tubes with their ends flush with the ceiling, which does not positively separate the wires projecting from the tubes nor avoidthe danger of a short circuit across the plaster.

As shown in Fig. VII the cap in some -cases may be, used without the block, the

tubes being arranged with their ends down:

wardly extending within the cap, giving a good insulation between the wires, to which the stripped ends of the cords 10 are soldered,

the joints taped in. the usual way, and the ent, is' screw-cavities 8 8, which are preferably filled i with insulating-cement.

At its inner corner the cap secure the cap in position.

3. In a rosette for electric wiring, the combination with a substantially circular, porcelain block having opposite curved recesses in its upper portion to receive the ends of the insulating tubes or conduits, metallic terminals provided with binding-screws arranged on the lower surface of the block adjacent to wire-holes communicating with the respective recesses, screws to secure the block in position, a porcelain cap to cover and surround the block, a boss on the lower surface of the cap, said boss being formed with an internal cavity and a central cord-hole, and screws to secure the cap in position.

at. In a rosette for electric wiring, the combination with a substantially circular, porcelain block having opposite recesses in their u pper portions, for receiving the ends of insulating-tubes, wire-holes in the bottoms of said recesses and opposite notches extending from top to bottom of the block margin between the recesses, of two metallic terminals arranged in seats on the lower surface of the block adjacent to the wire-holes, two binding screws in each terminal for the wire and cord respectively, a central circular reinforcement on the lower surface of the block having a depression, securing-screws for the block having their heads arranged in depressions adjacent to the notches, a porcelain cap, a circularmargin on the cap to surround the block, columns in the interior of the cap-margin formed with screw-holes and adapted to fit the notches, sectional reinforcing-ribs in the inner corner of the cap, a boss on the lower surface of the cap, said boss being formed with an inner cavity and a central knot-hole, and screws to secure the cap in position to cover the block.

5. In a wire-insulating device for concealed work, the combination with the wires suitably arranged in insulating-tubes, of the tubes arranged with their ends extending outwardly from the surface of a wall or ceiling, a cap arranged to cover the ends of the tubes, a boss on the cap provided with an internal cavity and a central cord-hole, and cords having their respective ends connected to the wire ends extending out from the tubes, said cords being knotted and the knot arranged in the cavity, with the cord ends extending downwardly through the cord-hole.

6. Ina wire-insulatin g device for concealed work, the combination with two insulatingtubes arranged with their ends extending downwardly a short distance beyond the surface of the ceiling in which they are supported, of wires arranged in the respective tubes and extending out therefrom, a porcelain cap, having a circular margin and a central cordhole, screws to secure the cap in position against the ceiling to cover the ends of the tubes, and a pair of cords having their respective ends connected to the wires, said cords being knotted in the interior of the cap and having their ends extending down through the cord-hole.

In testimony whereof I aliix my sign atureiu presence of two witnesses.
